STAR TREK: KLINGON FOREHEAD RIDGES

The Klingons are a humanoid warrior civilization originally from the planet Qo'noS but now a strong and revered interstellar military power seen throughout the Star Trek anthology. They are known for having distinct forehead ridges created by the Star Trek art department using latex prosthetics. This Klingon prosthetic has been painted brown to blend with Klingon facial features. The detail given to it also even includes pores on the skin. It was presumably used in Star Trek: Deep Space Nine or Enterprise given how well it is preserved.
